Digital Complexion Concealer can be applied before or after foundation, as desired. Shake the pen and then twist the applicator from the bottom to dispense the product. It’s advisable to use a Make-up Blending Plate or the back of your hand, if applying on yourself, to prevent cross contamination. Using your finger, brush or sponge, whichever your preference, blend the concealer into the skin using a patting technique until the liquid is absorbed into the skin and is seamlessly blended. The concealer can be layered, if required, to achieve higher coverage.
